WITNESSES: IN VE N 70R:

citizen of the United a remaining bulk the silage to'cattle or live-stock silo, which is objectionable and better quality of silage at, the bottom the bottom of the To all whom it may concern: j

Be it known that I, JosIAH G. SWAIN, a States, residing at Mooresville, in the county of Morgan and State of Indiana, have invented a new and useful Bottom-Delivery Silo,v of which the following is a specification, reference being had to the accompanying drawings, andrto thereon. I

This invention relates to a tank-lllre'hollow building commonly known as a silo and I in which live-stock food, commonly known as silage, is kept for vention having reference more particularly to a silo thatis soconstructed as to permit the contents thereofto be removed from the lower instead of bulk of silage. a An object of the invention is to provide an improved silo of such construction as to enable the stock feeder to obtain and feed without it being necessary to climb to the top of the the upper portion of the ticularly in the cold season of the year, in order to obtain the silage. Another object is to provide an improved silo of such construction that the older and may be conveniently removed while leaving the to become more mature. A still further object is to provide a safety feed-structure for silos that shall be adaptable to existing silos as'an improve ment thereto for the above-mentioned purposes, and whichshall be so constructed that the stock feeder safety without being exposed toinclement weather or the danger of being injured by the descending bulk of silage when the lower portions of the bulk are removed.

With the above-mentioned and other objects in view, the invention consists in a silo structure provided in the lower portion thereof with a bottom superstructure come prising a combined'wall and bottom portion that is in the form of an inverted hollow cone, the smaller'end of which rests upon silo and the larger end extends upward to the silo wall to constitute an inner inclined wallfor retarding the de-' scent of silage to the bottom, the inner wall having a doorway or Y which to remove the silage, and provided with a removable closure, the main wall of zrosrnrre. swam, or MQORESVILLE, rrmreiva;

the structure essentially comprising a suitable foundation '1 upon which is a silo bottom'orfioor 2 and a main wall '3 of suitable height, the latter preferably being cylindri cal; Preferably the bottom or floor has an elevated floor portion 4: arranged centrally with respect to the main wall 3. portion of the main wall is provided adiacent to the bottom or doorframefi to constitute amain doorway, a main'door 6 being closely fitted into the frame and hinged thereto, and the door may be secured in closed position by any suitable A suitable frame 7 1S placed upon and may suitably be device.

composed of woodand annular'in form so as to extend about the elevated port on l central position one side of the main doorway, a similar partitional wall 10 being secured to the adjacent opposite stud and extending to theopdrawings indicate like The lower portion, and it preferably floor 2 with a suitable A: hollow trundoorway for the inner wall and a gangway in which the stock feeder may work, and through which to draw thesilage for delivery through the main doorway; The studs are covered with suitable material, such as boards 11- fitted together and secured to the inner sides of the studs 8 to complete the inclined inner wall. The'space between the main wall and the inner walland bottom' portion is filled with suitable packing 12, such assawdust, to exclude air from the in terior of the space within the inner wall. The doorway of the inner wall is provided with a suitable removable closure which preferably comprises a suitable number of wooden boards 13 superimposed on edge on i the silo bottom or floor or on the frame 7 and extending behind the partitionalwalls 9 and 10, the outer side of each board preferably having suitable lug 14: thereon to be engaged by a crowbar or the like for forcing the board endwise when it is desired to remove it for gaining access to the silage.

It will be understood that various modifications may be made as to details of construction, and that the combined wall and bottom portion may be constructed and in.- serted in not only new but in old silos.

In practical use, the silo having been filled as is customary, with the doorways tightly closed the upper portion of the silage need not be disturbed with consequentrisk of that remaining on top deteriorating or becoming unfit. for use, "When it isdesired to feed the cattle orlive-stock the outer door is opened, after which one or moreof the lowermost boards, 13 may be removed first and subsequently others farther up may be removed if necessary to work. down a. sufficient quantity of the silage. When removing a board it may be forced endwise until one of its ends can be withdrawn from behind the back of the doorway frame, after which the board may be pulled out from behind the opposite portion of the frame. On removal of the silage from the bottom or floor portion a the bulk of silage should gradually descend ofits own weight,,or the under portions thereof'may be raked loose and removed'by the attendant without it being necessary for him to; enter the chamber under the bulk of silage. In case the silage descends too freely for the needs of the cattle, such as may pass through the doorway of the inner wall may remain-in the passageway between the inner doorand the outer door and permit the outer or main door to be .closed. The attendant can be sheltered from cold while working between the outer and inner doorways.

' Hav ng thus described the invent1on,what

is'claimed as new is- '1. A; silo appliance comprising anannular supporting frame, a plurality of studs secured to the frame and extending upwardly and outwardly therefrom, two partitional walls secured to two adjacent ones of the studs and extending outwardlytherefrom, and. a covering secured to the inner sides of the studs and covering the spaces between them excepting the space between thetwo. adjacent ones.

2.. A silo, comprislng a bottomfa main wall and an inclined inner wall supported on the bottom, the upper portion of the int ner wall having support against theinner side of; the main wall, the lower portion of the inner wall beingspaced apart from the mainwall to provide a worlnnans shelter chamber, there, being a doorway in each of the walls communicating with thechamber.

3. A silo comprising a bottom, a main wall and an inner wall on. the bottom, the inner wall being funnel shaped and having adeorway in the side of'its lower smaller portion, the main! wall having a doorway in its lower portion opposite the doorway of the inner wall, there being a passageway to shelter a workman between the two doorways, a, closure for the doorway of the main wall, aclosure for the doorway of the inner wall, and packing on: the bottom and between the inner wall and the main wall. 7,

4t. A silo comprising a bottom, a vertical main wall on; the bottomwitha'main door- I way therein adjacent to. the bottom, a door hinged to. the main wall to close the doorway, an inner wall within the main wall and extending at an inclination from the bottom of the silo; upwardly and outwardlyto the main wall above themain doorway to pro.- vide a workmanssafety chamber, the inner wall having a doorway therein opposite to the main doorway, and a plurality of superimposed closure boards inthe doorway of the inner wall and removably connected with the inner wall; 7
